If I have a doctor's appointment in the middle of the day, I might add it to my personal calendar with full details, but I still need to add an entry to my work calendar to show I'll be out of the office, possibly with a generic title like "Medical Appt".

I wouldn't do that personally. It would say "Busy" and nothing else - that is all the company needs to know.
